style='font-size:12.0pt'>The audio issue you mention is a known issue as a
result of some audio adjustments we've added in 1.3.<br>
<br>
The audio properties have been adjusted slightly in the 1.3 firmware to<br>
reduce side-tone and echo on the local and far-end equipment. In line with<br>
these adjustments we have added some configurable parameters that allow<br>
users to configure their own audio settings to best suit their needs. These<br>
parameters are only configurable via the .cfg file via a TFTP server and use<br>
the following syntax:<br>
<br>
headset tx gain:<br>
headset sidetone gain:<br>
handset tx gain:<br>
handset sidetone gain:<br>
handsfree tx gain:<br>
<br>
Each of these parameters can be adjusted by + / - 10 db<br>
<br>
Example 1:<br>
headset tx gain: -5 (reduce the headset transmit gain by 5 db)<br>
<br>
Example 2:<br>
handset tx gain: 10 (increase the handset transmit gain by 10 db)<br>
<br>
Please try adjusting these parameter.<o:p></o:p></span></font></p>
